MMPF0100 external sequencing

Hi Community,

 

is it possible to use the MMPF0100 without the sequencing functionality?

As we have a microcontroller on our board for power sequencing of additional regulators anyway, this controller could also take care of MMPF0100 during startup/shutdown.

My idea was to configure the MMPF0100 with all sequence registers set to 0 and setting the individual converters' registers via I2C during startup/shutdown. This would either simplify board bring-up and would also make it possible to nest the sequencing of MMPF and external regulators.

 

Unfortunately I don't have a suitable Board with MMPF0100 here to try it - so I post the question here...

 

 

Best regards,

Martin
